Re: [MW:31755] Facing crack in during overlay welding of Stellite 12 on Duplex material

Dear Suresh

Are you getting the crack during the deposition? Or after the job is cooled?

Dear Experts

During welding of Duplex grade material we are facing crack on the weld metal as attached in the photo. Below is the detailed process for reference

Process: PTAW

Base Material: ASTM 182 Gr.F55

Consumable: Stellite 12 (Powder)

PreHeat: Nil

Interpass: <200*C

Current: 128 to 145

Gas: Ultra Pure ARGON

Job Size: OD544 X ID 472 X Thk 36mm

Welding: Overlay weld on OD Surface alone

We are welding deposition thickness of 3mm. So as per this we are doing welding of 2 layer with multi pass, On welding second layer we found crack. Can anyone suggest where it is went wrong and why this crack is propagated. Please advice

 

In First layer- Total of 12 weld pass

In second layer- Total of 12 weld pass

Regards

Suresh
